Rule No(s): 1177 Date adopted/Amended/Rescinded: June 1, 2012

Rule Title(s): Liquefied Petroleum Gas Transfer and Dispensing

Date Submitted to ARB: August 14, 2012

If an Amended Rule, Date Last Amended (or Adopted): N/A (New Rule)

District Contact: Mr. Naveen Berry Phone Number: 909-396-2363 E-mail Address: nberry@aqmd.gov

Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

Rule 1177 is a newly-adopted rule that will reduce fugi tive VOC emissions associated with the transfer and

dispensing of liquefied petroleum gas (LPG) at residential, commercial, industrial, c hemical, agricultural and retail

sales facilities. The rule applies to the transfer of LPG to and from stationary st orage tanks, cylinders and cargo

tanks, including bobtails, truck transports and rail tank ca rs, and into portable refillable cylinders. VOC emission

reductions will be accomplished by requiring the use of low emission fixed liquid level gauges or equivalent

alternatives during filling of LPG- containing tanks and cylinders, use of LPG low emission connectors, the

implementation of a leak detection and repair program , along with associated recordkeeping and reporting to

demonstrate compliance. Rule 1177 will partially implement Control Measure MCS-07 (Application of All Feasible

Measures) of the 2007 Air Quality Management Plan (AQMP).

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

Complete this section ONLY for rules that, when implemented, w ill result in quantifiable changes in emissions. Attach referenc e(s) for emission factor(s)

and other information. Attach calculation sheet showi ng how the emission information provided below was determined

.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Category: No prior commitment

Inventory Year Used to Calcul ate Changes in Emissions: 2009 Area Affected: South Coast AQMD

Future Year Control Profile Estimate (Provide information on as many years as possible) : It is expected that the 6.1 tons of VO C emissions reduction will be achieved over a five year period beginning July 1, 2013

and extending until July 1, 2017 when full co mpliance with Rule 1177 is expected.CALIFORNIA AIR RESOURCES BOARD

Baseline Inventory in the SIP for the Control Measure: Not included in current 2007 AQMP baseline; to be included in

2012 AQMP baseline.

Emissions Reduction Commitment in the SIP for the Control Measure: N/A

Revised Baseline Inventory (if any): 8.6 tpd

Revised Emission Reduction Estimate (if developed): 6.1 tpd

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and

planning.

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY) Sources A ffected by this Amendment: A total of 5,625 small sources

consisting of: 25 LPG dealers/distributors; 3,300 retail trans fer and dispensing facilities; 200 bulk loading facilities and

2,100 facilities that transfer LPG into stor age containers using the gravity filling method

Percent in Nonattainment Area: 100 %

Number of Large (> 100 TPY) Sources Controlled: None Percent in Nonattainment Area: N/A %

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as

necessary) : N/A

Other Methods in the Rule for Achieving Emission Reductions are: Low emission equipment (d)(2) (A-D)

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): (d)(1)(A-C), (d)(2)(A-D), (e)(1-4) Work Practice Standards in Section(s):

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The net effect on air quality fr om the implementation of Rule 1177 is a projected 6.1 tpd reduction in fugitive

VOC emissions from the estimated 2009 Baseline emissions of 8.6 tpd. It is anticipated that these reductions will be

accomplished over a five year period as summarized in the t able below. This rule partially implements Control Measure

MCS-07 (Application of All Feasible Measures ) of the 2007 Air Quality Management Plan (AQMP).
